Abstract
A portable electronic device provides a compass bearing display juxtaposed with or superimposed on a camera viewfinder display. The device includes an image sensor and an electronic compass. When the device is held with the image sensor pointed in a generally horizontal direction, the displayed viewfinder image from the image sensor is combined with a graphic indicating a compass bearing corresponding to the imaging axis of the image sensor. The display may be presented as a linear scale to indicate off-axis headings as well.
